Another reliable method for ongoing tube placement verification is determining the pH of the fluid aspirated from feeding tubes. Gastric fluid is usually acidic, with a pH less than or equal to 5.5. 17 Respiratory secretions are almost always alkaline, with a pH greater than or equal to 6.
WebJun 1, 2024 · 5 L of aqueous solution of PEG-8000 (3 g/L) at pH 5 were used (the decrease in solubility in alkaline solutions is well known), together with a constant oxygen flow rate (4.0 L/min) at P = 0.35 bar; the ozone produced (theoretically around 5–6 g/L) was sent to the bottom of the glass reactor. WebApr 8, 2024 · Measuring the pH of gastric aspirate is considered the 'gold standard' in routine confirmation of NG tube placement prior to use. Typically, a pH of <6 would indicate an NG tube is in the stomach. See this previous Connected Care QuickHit for best practice for confirming placement of NG tubes.
